project description :

this project will produce an OFF THE GRID public light art work using piezo crystal technologies, solar & wind power.

harvesting energies from various sustainable sources, wind, solar and vibration depending on the site and local conditions.

The space beneath bridges. dark. functional. forgotten. ignored. negative space. pass over or under occasionlly loiter beneath.

train systems occasionally run on an overhead rail track or bridge. Vibrations produced can be used to trigger low energy LED lights. Bridge structures hinder air movement due to their obtrusive nature and guide it in specific directions.

By placing at regular intervals small modules containing LEDs and vibration sensors I intend to make a light installation that follows the path of a train on the underside of the bridge as the train moves along the rail track.

Simple efficient wind/solar/vibration harvesting can supply Good Vibrations with all its energy needs driving both the simple electronics and charging batteries. During the day harvested energy is stored in batteries. As dusk falls photosensors allow LEDs to be switched.

For this example a distance of 1/2 a km is planned for

Sensors and LED units will be placed every 2mtrs, piezo vibration, solar wind harvestors every 10mtrs
